10 Questions
What is the formula for the total time period of the output waveform in an astable multivibrator circuit?
T = 0.693 (RA + 2RB) C
How is the frequency of oscillation calculated in an astable multivibrator circuit?
f = 1 / 1.44(T)(RA + 2RB)C
What is the duty cycle of an astable multivibrator circuit?
Duty Cycle = D = (ton / T) * 100% = (RA / (RA + 2RB)) * 100%
What is the significance of the ON TIME in an astable multivibrator circuit?
ON TIME is equal to the charging time in the circuit.
What happens during the discharging time in an astable multivibrator circuit?
The capacitor discharges from 2VCC/3 to VCC/3.
In an astable multivibrator circuit, what is the formula for the OFF TIME of the output waveform?
